Interesting that you took this post to be entirely about romantic/sexual relationships, especially since a partner should not be solely responsible for assuaging your lonliness.
Even if everyone had a partner/spouse male loneliness would still be a massive issue because men aren’t socialized in a way that equips them to have emotionally intimate platonic friendships. If my wife was my ONLY friend, I’d still be very lonely. Furthermore, even if I wasn’t in a relationship, I wouldn’t be lonely because of the friends I have.
WTF are you talking about.
